VAPO'RIZING DEVICE.

Application. filed August 11, 1920.

To all whom it may concern:

Be it known that I, FRANK C. DoRirnN'r, a. citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in vaporizing Devices, of which the following is a full, clear, and exact description.

The present invention relates to a vaporizing device which is particularly designed .to vaporize liquid material used as a deodorant, disinfectant or medicinal remedy useful in the treatment of the human respiratory passages.

The device finds particular utility as an apparatus for deodorizing and purifying the air in buildings, theaters and similar assembly halls, and because of the efficiency of the vaporizing action obtained, the vaporized material is disseminated rapidly and ear tensively.

Thorough vaporization is obtained not only by mechanically breaking up the particles of the liquid used, but the heat generated by the motor of the suction and expelling fan is utilized to heat the exit portion of the device and effect a further and more complete vaporizing action.

The foregoing objects are accomplished while maintaining the proportions of the device as to make the same of simple as well as light construction and readily portable.

Reference should be had to the accompanying drawings forming a part of this specification in which Fig. 1 is a sectional elevation; Fig. 2 is a bottom plan view; Fig. 3 is a top plan view of a portion of the machine; Fig. 4 is a plan view of the suction fan; Fig. 5 is a plan view of the top plate of the receptacle.

Referring to the drawings, 1 indicates a container which has a side wall portion; a top wall 2 and a bottom 3 which is preferably made with a raised central portion so that the liquid contents of the container will have a tendency to flow toward the outer edge thus enabling the last portions of the liquid which may be used in the container to be utilized.

Depending from the cover 2 is a partition member 4 which extends parallel with the side wall of the container to a point adjacent the bottom member 3. This partition member forms an air conducting chamber which may be designated at 5, which air Serial No. 402,884.

conducting chamber extends entirely around the inner wall of the container.

The top member 2 is provided with a plurality of slot like openings such as indicated at 6. and controlling these openings. is a cover member 7 which is mounted to have a turning member on the top 2. The top member 2 has an upstanding collar 2 and the cover member has an upstanding flange 7. These are in engagement and the cover member 7 turns about the upstanding flange 2 The cover is provided with a plurality of openings such as indicated at T and inasmuch as the cover 10 may be turned, the openings 7 and 6 may be brought into registry so as to make a free opening for the passage of air. Obviously the cover 7 may be adjusted so as to effect a partial aligning of the openings 6 and 7" and this may be effected to any desired extent to control the passage of air through the openings described.

The upstanding flange 2 which is formed as a part of the cover 2 receives a casing which may be generally indicated at 8. This casing has a tubular extension 9 which fits within the upstanding flange 2 This casing is formed preferably in two halves, as indicated at 8 and 8", these two halves bein secured together by any suitable means. Within the casing is a fan such as indicated at 10, the fan being preferably arranged so that its axis is substantially in line with the annular or circular neck portion 9. The portion 8 of the casing 8 has an extending portion 8 which is of a proper size to receive the stator and rotor of a motor for operating the fan. The motor shaft is extended so that the fan may be mounted upon the same as indicated at 11. Inasmuch as the portion 8 of the casing is made integral with the portion 8*, the heat which is generated incident to the use of the motor, will be conducted by the sleeve like extension 8 from the motor to the casing 8 and inasmuch as by the action of the fan air is passing through the casing 8, the heat is conducted by the air from the casing 8. i

This action results in a two fold usefulness. In the first place the motor runs cool so that if the apparatus be operated for considerable periods of time, there is no danger of overheating the motor. This is an important consideration when. it is remembered that in a device of this character the motor cannot be large and must be positioned with respect to a proper placement of the .tan which it operates, and furthermore, through the necessity of positioning the motor on top as it were of the apparatus, it is desirable to protect the tan and the heat which is thus imparted to-"the vapor ladened' air serves to more etfecti-vely vaporize the material with which the air is ladened.

'The casing 8 is provided with an exit end 8 which is arranged substantially tangential to the periphery of the tan. llhi's exit portion 9 may be left open as it is inthe case where the apparatus is being used for the purpose of disintecti 1g and purifyingfthe air in a room or hall or hu-i'lding,'but when it is desired to use the apparatus inthe treatment of diseases of the respiratory'passages a plug 13 may be insertedin the part8 which plug carries a hose It with a mask 15, which mask is placed over the mouth and nose of the patient being treated;

' Withinthe wall t there is a depending screen member 16'. This is preferably cylindrical in shape and the lower end closed preferablyby'means ota conical bottom piece 19'. This form ot 'bottom'piece is a van-tageous in'that it some particles of l uid pass through the screen 16, and coll'e'otwithin the screen member, the particles of liquid will not tend to collect within the tube, but rather will flow down the slanting walls 17 and return to-the body of liquid within the container. The cylindrical screen member 1'6 is fastened to a collar 1-8 which i-sffrictionally held within the portion 9 of the casing 8.

It willbe seen that the casingS and the f screenmember 16 may be'removed as a unit 'itromthe container, and alsothecasing being made-in two parts, permits ready access to all the working parts of the ap- *pa-ratus;

The bottom member 3 of the container i s removable and isheld to the'side wall portion-o-fth-e container by means of clampijngmembers such'as indicated at 19 which are held in place by screws 20.

"In the operationof thmdevice the liquid to-be vaporized isplacediwithin the contai-ner l'anda sufficient-portion isplaced therein so as to sea]. the lower end of the n partition-24:, The fan is started and creates f l ti it WiP P--tlleW 1l raw =lad ened air which is being forced by the air through the openings 7 and 6 and through the air passageway 5, which air bubbles up through the liquid in the bottom of the container and as it bubbles up the air becomes ladened with the vapors and small particles of the liquid through which it is passed.

The vapor ladened air next passes through, the screen member 16 which serves to break up the particles of liquid which may be mechanically carried by the air-and generally to cause a more thorough mixture of the air and the vapor. The vapor la dened air as it passes through the casing 8,

takes up the heat which has been conducted 1 to it from the portion of the casing-which surrounds the motor and so provides an in.- creased assistance towsecure complete vaporization.
